My 66st has been working fine when connecting to USB ports on my desktop, but now (just as I'm about to embark on a 4 week holiday with it), I discover that it won't recognise it is connected to a USB port on my tablet (that I take on my travels), The GPS recognises it is connected to power, but never offers me the option to switch to USB mode - so I can't extract my tracks and waypoints.

1. Has anyone experienced this before with USB ports ?
2. Can anyone think of other ways of extracting tracks and waypoints ?

It's Windows 10. I suspect/know that the USB port is limited in its power supply capacity (from trying to connect my phone, and camera to it in the past). I eventually did get it to connect to the 66st by my usual method of "faffing-about".
